Definition. Flax, cellulose and wood fibre are the strongest biobased insulation choices. Among the biobased materials in the study, flax board (roof, MPG €0.012/m²/year), cellulose (cavity, 1.8 kg CO₂-eq/m²) and wood fibre board (ECI €0.95/m²) score best on environmental performance.
All three combine low environmental cost with low CO₂ emissions and, for flax board, high reusability. New Economy’s circular insulation study for Amsterdam reports this.
